RF2442

The RF2442 is a low noise amplifier with a very highdynamic range designed for the receive front end of digitalcellular applications at 900MHz, 1900MHz, and2400MHz. It is designed to amplify low level signals withminimum noise contribution while operating in the harsh,interference-rich environments of newly deployed digitalsubscriber units. The device also functions as an outstandingPA driver amplifier in the transmit chain of digitalsubscriber units where low transmit noise power is a concern.The device supports trade-offs between linearityand current drain. The designer has control of thesetrade-offs with the choice of an external bias resistor. TheIC is featured in a standard miniature 8-lead plastic SOP package.
